My uterus became very tight and uncomfortable about two hours ago and has remained tight since. I went to the grocery store during this time and it was uncomfortable to walk and seemed to make my uterus feel even tighter. I'm not having regular contractions, so I can't time them. Rather, my uterus is remaining VERY tight. In addition, I'm having low back pain, I felt "wet" but I think it was just discharge because it didn't smell like amniotic fluid or urine, and my feet are swelling ONLY when I am standing. Ideas?
Background info: I'm 34. This is baby #5. Baby #1 was a Cesarean and the other 3 were UC's. I've never had issues with preterm labor. Baby is active. Blood pressure is fine.
Should I be concerned?
